Hundreds of people gathered at Cal Poly on Friday for a climate action rally, one of hundreds being held in cities all over the world.
Demonstrators are hoping to raise awareness about climate change and urge lawmakers to take action.
"The time is now, the time is yesterday, the time is four years ago, the time is ten years ago but it needs to finally be now. Something needs to happen, something needs to give," said Ellia Simmons, Cal Poly student.
"Show solidarity with our leaders who are paving the way of the future and really remind them they need to solve this crisis and that we need to work as a group to solve this crisis," said Declan Galli, lead organizer of the Cal Poly SLO Climate March.
People from multiple generations showed their support during the march.
Sophia Ortiz, a Cal Poly student and communication coordinator for Sunrise, said there are little things people can do to make a difference.
"The thing about climate change and the movement, it's the really small choices. It's the really small impacts you don't even realize you're having when you support a certain brand or you support packaging that isn't sustainable," Ortiz said.
The hope is rallies like this will urge others to take action.
"Raising awareness, letting people know that we're here, we're loud, we care and this is important to so many people and it should be important to our legislators," Simmons said.
"If you're a senator or a representative that is questioning whether or not you should stand up to climate change, you have the voting power behind you that will vote you back in if you do and if you don't, the voting will do the same and we're going to vote you out," Galli said.
Those in attendance hope government leaders and the world hear their chants before it's too late.
